1. ABOUT THE DATASET ------------ Title: Data from perennial flower margins reduce orchard fruit damage by rosy apple aphid, Dysaphis plantaginea (Homoptera: Aphididae). Creator: Charlotte Howard Organisation(s): Centre for Agri-Environmental Research, School of Agriculture, Policy and Development, University of Reading, Earley Gate, Reading RG6 6AR, UK Rights-holder: University of Reading Publication Year: 2024 Description: Data were collected from ten conventional commercial apple orchards in Kent, UK. They include the number of Rosy aphid infested shoots, the number of apples, and the number of rosy aphid damaged fruits on 45 trees per orchard which were systematically searched (2021 and 2022). They also include the number of bait aphids remaining on sentinel bait cards in the same orchards on a subset of those trees (2021). This also includes the abundance of natural enemies and other taxa of interest found during the surveys.
